Unable to run two instances of BPMS or BPMS and RHPAM on the same machine

Issue

• Unable to run both BPMS and RHPAM on the same machine
• When I tried opening BPMS 6.4 and RHPAM 7 in parallel with different port in my laptop locally, not able to do so.
• Unable to run two instances of BPMS on the same machine;

• When starting the second instance of BPMS the following error is logged:
